Jason notices that his shower is covered in a strange green slime. His friend FeFe tells him that coconut juice will get rid of the green slime. Jason decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.
Answers
Answer:
This question is incomplete, the question is asking to identify the following aspects of the experiment:
Dependent variable: Amount/appearance of green slime
Independent variable: Coconut juice
Constant: Same shower
Control group: half of the shower sprayed with water
Experimental group: half of the shower sprayed with coconut juice
Explanation:
The independent variable in an experiment is the variable that is changed or manipulated in order to bring about an effect. In this case, the independent variable is the COCONUT JUICE.
Dependent variable is the variable being measured by the experimenter in an experiment. In this case, the dependent variable is the AMOUNT/APPEARANCE OF GREEN SLIME.
Experimental group is the group that received the experimental treatment in an experiment. In this case, the experimental group is the HALF PART OF THE SHOWER SPRAYED WITH COCONUT JUICE.
Control group is the group that does not receive the experimental treatment in an experiment. In this case, the control group is the HALF PART OF THE SHOWER SPRAYED WITH WATER.
Constants in an experiment are those variables that are kept the same for all groups in an experiment. In this case, a constant is the SAME SHOWER USED THROUGHOUT.

If a plant wiht purple, axial flowers and green, inflated pods is heterozygous for all four genes, how many different ype sof gametes can it produce?
Answers
Therefore, the plant can produce 16 different types of gametes. Each gamete will have a unique combination of alleles for the four genes.
The plant is heterozygous for all four genes, which means it has two different alleles for each gene. To determine the number of different types of gametes the plant can produce, we need to consider the different combinations of alleles for each gene.
Let's represent the alleles as letters:
Gene 1: Aa
Gene 2: Bb
Gene 3: Cc
Gene 4: Dd
To determine the number of different types of gametes, we multiply the number of possibilities for each gene together.
For each gene, there are two possible alleles, so for each gene, there are two possibilities. Since there are four genes, we multiply these possibilities together:
2 (possibilities for Gene 1) * 2 (possibilities for Gene 2) * 2 (possibilities for Gene 3) * 2 (possibilities for Gene 4)
= 16 different types of gametes
Therefore, the plant can produce 16 different types of gametes. Each gamete will have a unique combination of alleles for the four genes.
Let's consider an example: If we represent the different types of gametes as letters, we could have:
ABCD
ABcd
AbCD
Abcd
aBCD
aBcd
abCD
abcd
These are just a few examples of the different combinations of alleles that can be present in the plant's gametes. There are a total of 16 possible combinations.

protein shape is crucial to its proper function. students have difficulty grasping this idea and how the specific sequence of amino acids determines the shape and how that, in turn, affects protein function. as an example, sickle cell disease is a lethal disorder caused by just a single amino acid change in the primary structure of the protein hemoglobin. briefly explain how the words tasty and nasty can serve as a good analogy for a teacher trying to explain this concept to students.
Answers
The words tasty and nasty serve a good analogy for explaining the concept or protein shape and its essentiality for the function. This is because the word tasty creates image of some delicious food in the mind. However, replacing just one letter 't' from the word with 'n' changes the entire meaning and depiction. This is how the primary structure of proteins functions. Change in a single amino acid can change the complete primary sequence.
Amino acids are the organic molecules that are essential for protein formation in the living organisms. The basic structure of amino acids i s composed of a amino group, a carboxylic group, a hydrogen atom and a variable R group all attached to the alpha carbon atom.
Primary structure of proteins is composed of a linear chain of sequence of amino acids all boned together by peptide bonds. The primary structure sequence is very crucial for the structure and function of the protein.

What is Linnaeus classification system?Linnaeus grouped all living things into two main groups (Kingdoms) that he dubbed "plants" and "animals" in an effort to utilize a "natural" classification system or taxonomic ordering. Therefore, it was necessary to categorize all recently discovered organisms into one of these categories initially. It "felt natural," He categorized things into seven layers of groups within groups, including the kingdom, phylum, class, order, family, genus, and species.

In the given pre-mRNA sequence, we are instructed to mark the splice sites and underline the sequence of the mature mRNA. The splice sites are indicated by the symbols "/" and "", representing the 5' and 3' splice sites, respectively.
Analyzing the sequence, we can identify the locations where the splice sites occur. The 5' splice site is indicated by "AG/GUAAGU" and the 3' splice site is indicated by "AG\GN". Since there may be more than one 5' and 3' splice site, we need to mark all the occurrences.
After marking the splice sites, we underline the sequence of the mature mRNA. The mature mRNA is formed by removing the intron sequences, which lie between the splice sites. In this case, the underlined sequence represents the mature mRNA after splicing. The 5' splice site(s) is marked with a forward slash (/), and the 3' splice site(s) is marked with a backslash ().
The underlined sequence represents the mature mRNA after splicing. In this case, the underlined sequence is:

The ability to taste PTC is due to a single dominant allele "T". You sampled 215 individuals in a biology class, and determined that f150 could detect the bitter taste of PTC and 65 could not.
What is the predicted frequency of the recessive allele (t)?
What is the predicted frequency of dominant allele (T)?
In a population of 10,000 people, how many would be heterozygous (assuming Hardy-Weinberg equilibrium)? Homozygous dominant? Homozygous recessive? Calculate all of the potential frequencies.
Answers
The genotypic and allelic frequencies of population in hardy-weinberg equilibrium remain the same through generations. f(T) = 0.453. f(t) = 0.547. Homozygous dominant individuals = 2050. Heterozygous individuals = 4950. Homozygous recessive individuals = 3000.
What is Hardy-Weinberg Equilibrium?The Hardy-Weinberg equilibrium is a theory that states that a population in equilibium is not evolving (no evolutive forces are acting on it) and its genic and genotypic frequencies remain the same generation after generation.
Assuming a diallelic gene,
⇒ The allelic frequencies in a locus are represented as p and q.
The frequency of the dominant allele p(X) is p The frequency of the recessive allele p(x) is q⇒ The genotypic frequencies after one generation are
p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).To calculate these frequencies, we can use the following formulas,
The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
1) N = 215 individuals
150 Individuals could taste PTC ⇒ TT and Tt
65 individuals could not ⇒ tt
To get the frequencies, we will divide the number of individuals expressing each phenotype by the total number of individuals.
Phenotypic frequencies
Capability to taste PTC ⇒ 150/215 = 0.697 ≅ 0.7
No capability to taste PTC ⇒ 65/215 = 0.302 ≅ 0.3
The phenotypic frequency of individuals who can not taste PTC (non-taster) is equal to the genotypic frequency -F(tt)-. We can use this value to get the allelic frequency -f(t)- by taking the square root.
F(tt) = q² = 0.3f(t) = q = √0.3 = 0.547Now we can get the dominant allele frequency -f(T)- by clearing the equation p + q = 1.
p + q = 1
p + 0.547 = 1
p = 1 - 0.547
p = 0.453
f(t) = 0.547f(T) = 0.453Now, by using these allelic frequencies, we can calculate the frequency of individuals TT, Tt, and tt.
F(TT) = p² = 0.453² = 0.205
F(Tt) = 2pq = 2 x 0.453 x 0.547 = 0.495
F(tt) = q²= 0.547²= 0.3
In a population of 10,000 people there will be,
Homozygous dominant individuals = 0.205 x 10,000 = 2050Heterozygous individuals = 0.495 x 10,000 = 4950Homozygous recessive individuals = 0.3 x 10,000 = 3000You can learn more about hardy-weinberg equilibrium at

Eutrophication involves the overpopulation of aquatic ecosystems with plant and animal life.
d. Eutrophication is rarely caused by human activity.
Answers
Answer:
b
Explanation:
Eutrophication occurs when excess nutrients like phosphorus from agricultural fertilizers are carried off into aquatic ecosystems. Since phosphorous is one of the limiting nutrients to plants, its excessive amounts result in a drastic increase in algal growth in the water system.
Step 2
As these plants decompose, a high amount of oxygen is used up resulting in a decrease in oxygen levels in the aquatic system. A very low level of oxygen in the water is detrimental to many aquatic organisms.
